To get voice chat (VC) in Roblox, start by ensuring you are at least 13 years old. Next, verify your email and phone number, then set up two-factor authentication (2FA) on your account. If you are in the United States, you might get VC without needing an ID.
In Roblox Studio, go to Game Settings, then the Options tab, and toggle the voice chat switch to enable it. Make sure your game has servers with 30 or fewer max players. If you are outside the United States, you may need to verify your identity using an ID to access voice chat.
Some users have reported success by creating a new account and meeting these requirements, though this isn’t guaranteed. Your location and other factors can affect whether this method works for you.
